Here's and interesting bug(?) we found over the weekend that deals with distributing levels and times over selected channels. It's repeatable and is not fixed as of yet in 10.3.1 (Channel numbers are arbitrary, just the ones we were using at the time):

Working Result - Distributed levels and times over 101-109
101-109
@ 10-100
@ (in time)
0-5

Rob, I love the thought of being able to treat groups as "blocks". this would be very cool and was briefly discussed earlier in relation to effects but could be very powerful as a general concept. The problem here is the syntax to determine when the "flatten" and when not to. There are bunches of cases where you'll want which ever is not the default.

If I go Group 1 THRU Group 3 @ 1 to 100
do I see:
1) Every channel at a different level?
2) 1-100@1%, 101>200@50%, 201>300@FL ?

You will see (1) every channel at a different level.
Groups are just recalled as individual channel selections.
I definitely see the utility in (2), but things were never designed to support that concept.
Saying that, besides the situation just described, can anyone think of other cases where this behavior would be handy?
I'm thinking potentially in effects, but not sure.

Consider several electrics with differing numbers of fixtures and the desire to do a Upstage to downstage ramp. If each electric is a group then the syntax of [group] 1 [thru] [group] 4 [@] 30 [-] 90 [enter] is the answer if we had Rob's "Flat" groups.

If I want to wipe top to bottom one way could be to have a group for each horizontal 'row'.

I could then go:
GROUP 1 (top row) THRU GROUP 32 (bottom row) TIME 1 to 10/5

(provided group a THRU group b is a valid syntax... don't know if it is....)

However, from your earlier answer this wouldn't do what I wanted. So I'd need to do something like:

GROUP 1 THRU GROUP 32 FLATTEN time...

except that implies it would flatten the whole selection rather than each individual group. It's another syntax where the command line needs commas or brackets or something to let you explain the order you want to work in, just like mathematics....
